Our invention relates tofiwrapping ma chines and more particularly toconveying apparatus for.p1pe wrapping maclunes-of the characterdescribed in our co-pending application Serial Number d51,227

a The principal ;objeets ofourinvention are to provide means forstabilizing a wrapping machine during its longitudinal movement along aconduit, to provide means for facilitating the removal of a machine froma conduit, and to provide for transportation of the dismounted apparatusfrom one location to another. I

In accomplishing these and other objects of our invention wehaveprovided improved details of structure the preferred form of which .isillustrated in the accompanying drawings, wherein: v

Fig. l is a perspective view of a pipe-wrapping machine mounted onaconduit'andsupported,.partia lly, by a stabilizing wheel running on theground.

Fig.2 is a perspective view of the machine dismounted from the conduitand supported on truck wheels for transportation.

Fig. 3 is a perspective viewxof an armor shaft used both for supportingthe stabilizing wheel and for facilitating dismounting andtransportation of the machine. a

Referring more indetail'to the drawings:

1 designates a conduit adapted to receive a pipe-wrapping machine,generally designated 2, including a frame 3 provided with rollers 4 forlongitudinal movement of the apparatus on the conduit.

An extension 5 of the frame supports a motor 6 for driving tractionwheels 7 of the machine through chains 8 and 9 operably connected by acountershaftt), through gears 10 and through a clutch 11.

Mounted on the forward end of the frame is a yoke member 12 forrotatably receiving a carrier ring 18 which is driven from the motorthrough a train of gears 14 and through aring gear 15 fixed to thecarrier.

The carrier is provided with a removable section 16, and tie plates 17extending across the ends of the yoke members, are detachably securedthereto to adapt the apparatus for convenient mounting or dismountingfrom a conduit.

A spool 18 for wrapping material 19 is supported from the carrier-ringso that retation of the carrier and simultaneous longitudinal movementof the machine will wrap material from the spool in spiral form aroundthe conduit. 7

A wiping apron 20, further supported from the carrier on a rod 21,'isyieldingly anchored to the spool element by a hook 22 for urging thewrapping material into intimate engagement with the conduit.

The apparatus thus far described does not constitute a part of ourpresent invention but is disclosed and referred to in connection withour invention to present a complete embodiment of the apparatus whenequipped with the stabilizing and transportation means now to bedescribed in detail.

The means for stabilizing the machine as t is moved longitudinally onthe conduit includes a socket member 23, preferably comprising arelatively short end of pipe welded, as at 24, to the upper surface ofthe frame and in transverse relation to the conduit. This socket memberis adapted to receive an arm or shaft 25 directed laterally from themachine andwhich is secured in the socket by a pin 26 removably extendedthrough aligning openings 27 and 28 in the socket member and shaftrespectively;

Threaded on the outer end of the shaft 25 is a head or T fitting 29,positioned in vertical relation'to the apparatus and a tubular stem 30adapted to extend through'said fitting is welded or otherwise secured atits lower end to a fork 31 for rotatably mounting a stabilizing wheel 32therebetween on a transverse shaft or axle 38; cotter pins 34 or thelike extended through the axle adjacentits ends serving to retain thewheel in the fork.

The stem 80 is further provided with a series of transverse apertures 35and across pin 36 is selectively extended througheither of saidapertures to support the machine through the shaft 25 and T fitting,thereby preventing rocking of the wrapping machine by blots 40 andhaving downwardly inclined portions l1 twisted at right angles to theremainder of the arms and provided near their 7 outer ends with aligningopenings 42 for receiving a shaft or axle l3 adapted to rotatably carrythe wheel 37.

At angular bracket 44: is fixed to the yoke 12 preferably by bolts 45,and a pair of arms 46, having openings l7 adjacent their lower endsaligning with an opening 48 in the an-' gular bracket, are secured bybolts 49 to a vertical standard 50 of the frame.

A transverse shaft or axle 51 is extended through aligning openings inthe angular bracket lfand pair of arms 46, and through the hub of thewheel 38. Cotter pins 52 and washers 58, as shown in Fig. 2, may

be used for retainingthe'shafts in the re- With a wrapping machinemounted on a" conduit in operable position as shown in Fig. 1 the shaft25 is anchored in the socket member 23 by the pin 26, and together withthe stem inserted through the T fitting 29 transmits a portion of theweight of the .machine to the stabilizing wheel, thus preventingexcessive swaying of the machine on the conduit. 7

When a string of pipe has been wrapped and it is desired to transportthe machine to another pipe string, the section 16 of the carrier ringand the plates 17 are removed to permit dismounting of the machine fromthe conduit. By then removing the pin 26 the stabilizing assemblyincluding the shaft 25 are detached from the apparatus and disassembled.The shaft 25 is next inserted in the socket member 54 for rotating theframe on the conduit to engage the truck wheels 37 and 38 with theground as shown in Fig. 2. As soon as the weight of the machine rests onthe truck wheels the apparatus may be readily removed from theconduit-and transported for further pipe wr'apping operations. Ifdesired, a handle bar 56 may be inserted through the T fitting 29 tofacilitate these operations.

What we claim and desire to secure by LettersPatent is:

1. In combination with a pipe wrapping machineincluding a frame,brackets extending laterally from the frame, means for securing thebrackets to the frame, wheels rotatably mounted on said brackets, andmeans on the machine for rotating the frame on the pipe to engage saidwheels with the ground, and for effecting transportation of the machine.

2. In combination with a pipe wrapping machine including a frame,brackets extending laterally from the frame, means for securing thebrackets to the frame, wheels rotatably'mounted on said brackets, asocket member secured in angular relation to the frame, and a shaftadapted for seating in said socket member to rotate the machine on thepipe for engaging said wheels with theground and for eflectingtransportation of the machine.

"3. In combination with a pipe wrapping machine including a frame, abracket extending laterally from the frame, means for securing thebracket to the frame, a wheel rotatably carried by the bracket, andmeans permitting rotation of the frame of the pipe wrapping machinewhile on the pipe so as to bring said wheel into position fortransporting the machine away from the pipe in adirection at an angle tothe longitudinal lay of the pipe.

4. In combination with a pipe-wrapping. machine including a frame, pairsof brackets extending laterally from the frame, means for securing thebrackets to the frame, a wheel rotatably mounted between each pair ofbrackets, and means on the machine for rotating the frame on the pipe toengage said wheels with the ground for transporting the machine. Intestimony whereof we afiix our signatures.
